Form 15 and Form 16 encumbrance certificate are the two formats of encumbrance certificate (EC) issued by Karnataka sub-registrar offices. Form 15 is the detailed EC that lists every registered transaction, mortgage, sale or lien on a property for the period you apply for. Form 16 is the simple EC that only states whether any encumbrance exists on the property, without listing the details. According to the Registration Act 1908, all registered transactions must be indexed and made available for public search, which is why every sub-registrar office in Karnataka can issue either form on payment of the prescribed fee.
I've been doing property due diligence in Bangalore for over 20 years, and I'll tell you this straight: most buyers don't even know there are two forms. They walk into the sub-registrar office, ask for an EC, pay the fee, and walk out with whatever the clerk hands them. Then they hand me a Form 16, which says 'no encumbrance', and assume the property is clean.
That's a mistake I've seen cost people lakhs. So let me explain both forms properly, when to use each, and how to read what you get.
What is Form 15 in an encumbrance certificate?
Form 15 is the detailed encumbrance certificate. It lists every single registered transaction touching that property for the period you have applied for - sales, gifts, mortgages, releases, court attachments, leases, everything that passed through the sub-registrar's office.
Each entry shows the document number, the date of registration, the nature of the document, the parties involved, and the extent of the property affected. If a bank mortgage was registered on your flat in 2018 and released in 2021, both entries will show in Form 15.
This is the form you want when you are actually buying. It gives you the paper trail.
What is Form 16 in an encumbrance certificate?
Form 16 is the simple EC. It does not list transactions. It just says whether any encumbrance exists on the property for the period searched, or whether the property is free of encumbrance.
In practice, you get a short statement: 'No encumbrance found for the period X to Y', or 'Encumbrance exists' with no detail.
Form 16 is useful for a quick sanity check. It is not useful for deciding whether to buy a property worth crores. If Form 16 says there is an encumbrance, you have no idea what the encumbrance is. Is it a live mortgage? A court attachment? A lease? You won't know until you pull Form 15.
What is the difference between Form 15 and Form 16 encumbrance certificate?
Here is the comparison I show every client across my desk.
| Point | Form 15 EC | Form 16 EC |
|---|---|---|
| What it shows | Full list of all registered transactions | Only whether encumbrance exists or not |
| Detail level | Document number, date, parties, nature of transaction, extent | One-line status |
| Best used for | Before purchase, before loan, before registration | Quick preliminary check only |
| Period coverage | You choose the search period | You choose the search period |
| Who issues it | Sub-registrar office or Kaveri portal | Sub-registrar office or Kaveri portal |
| Cost in Karnataka | Approximately Rs 30 per year of search plus user charges | Same fee structure |
| Reliability for purchase | High, if read by a lawyer | Low on its own |
Takeaway: If you are buying, insist on Form 15. Treat Form 16 as a first look, not a final answer.
One more thing. The fee structure is similar, so there is no cost reason to settle for Form 16. The only reason buyers end up with Form 16 is that they didn't ask for Form 15 by name.
How do you apply for Form 15 and Form 16 encumbrance certificate in Bangalore?
You have two routes - online through the Kaveri portal, or in person at the sub-registrar office that has jurisdiction over the property.
For a Bangalore property, the relevant sub-registrar office is the one where the property falls. Jayanagar, Whitefield, Rajajinagar, Shivajinagar, Gandhinagar - each has its own office and its own records.
Here is the step-by-step for the online route.
- Go to the Kaveri online services portal run by the Karnataka Department of Stamps and Registration.
- Create a user login if you don't have one.
- Select 'Encumbrance Certificate' under the services menu.
- Enter the property details - district, taluk, village or ward, survey number for land, or flat and building details for apartments.
- Choose Form 15 or Form 16.
- Enter the search period. I usually recommend 30 years for land, 15 to 20 years for apartments.
- Pay the fee online.
- Download the EC once it is generated.
If the property records are old or the survey numbers have changed, the online search may return no data or partial data. In that case you have to go to the sub-registrar office and apply manually. This happens more often than people think, especially with ancestral land in and around Bangalore.
When we run these checks as part of property document verification in Bangalore, we usually pull both forms, cross-check the entries against the mother deed and the khata, and flag anything that doesn't line up. That cross-check is where the real value sits.
What documents do you need to apply for an EC in Karnataka?
For the online route, you don't need to upload much. You need the property identifiers. For the offline route, the sub-registrar office will typically ask for:
- Application form for EC (available at the counter or downloaded from the Kaveri portal)
- Copy of the sale deed or title deed of the property
- Copy of the khata certificate or khata extract
- Property tax paid receipt (latest)
- Identity proof of the applicant - Aadhaar, PAN or voter ID
- Proof of address, if the applicant is not local
- Fee payment receipt
If you are applying for someone else's property as a prospective buyer, you will also want a letter of authority or a copy of the agreement to sell, so the office knows why you are searching.
Can you apply for an EC without being the owner?
Yes. EC records are public under the Registration Act 1908. Any person can apply for an EC on any property by paying the fee and giving the correct property identifiers. This is exactly how buyers do due diligence before purchase. You don't need the seller's permission to check.
Can you get Form 15 and Form 16 online in Karnataka?
Yes, both forms are available through the Kaveri portal for most properties where records have been digitised. For older properties, especially agricultural land, you may still need to visit the sub-registrar office. If the online system throws an error, don't assume the property is clean. Assume the records need manual search.
How long does an encumbrance certificate take in Bangalore?
Online, a clean digital search usually generates the EC within 15 minutes to a few hours. If there is a queue, the same day or next working day.
Offline at the sub-registrar office, expect 3 to 7 working days depending on the office load. Some offices in Bangalore are faster than others. During peak registration season, the wait can stretch longer.
When clients come to us with a token advance deadline ticking, we usually return a title opinion in two to three days because we run the EC search, khata check and mother deed review in parallel, not one after another. Urgent checks we turn around the same day.
What red flags should you look for in Form 15?
This is where 20 years of reading EC records pays off. Here is what I look for, in order.
- Unreleased mortgage: A bank mortgage registered but no corresponding release deed. The bank still has a charge on the property.
- Multiple sale deeds on the same property: If the same survey number or flat shows two sale deeds to two different buyers, you have a title dispute waiting to explode.
- Court attachment: Any entry showing attachment by a court or authority. The property is effectively frozen.
- Gift deed you didn't know about: A gift that transferred the property away from the seller's family and was never disclosed.
- Partition deed with unclear shares: If the property was partitioned and the shares are not cleanly defined, every co-owner's consent becomes necessary.
- Long gap in the chain: If the EC shows nothing between 1990 and 2005, ask why. Either the records are missing, or transactions happened that were never registered.
- Lease registered for more than 11 months: A long lease can survive the sale and bind you.
A client came to me last year, ready to register a flat in Whitefield. The seller's Form 16 said no encumbrance. I pulled Form 15 anyway. There was a mortgage registered in 2016 in the name of a private finance company, never released. The seller claimed it was settled. The EC showed otherwise. We held the payment until the release deed was registered. That one search saved my client from buying a property with a live charge on it.
What happens if you skip the EC check before buying?
Skipping the EC is how people end up in court for years. I've seen it dozens of times.
If you buy a property with an unreleased mortgage, the bank can enforce its charge against the property even after you have paid the seller in full. Your sale deed is valid between you and the seller, but it doesn't wipe out a prior registered charge.
If the property is under court attachment, your registration can be challenged. You may end up as a party to litigation you never asked for.
If there is a prior sale deed you didn't know about, you have a straight title dispute. Two buyers, one property, and the courts decide who gets it.
The cost of a Form 15 search is a few hundred rupees. The cost of not doing it can be the entire purchase price plus legal fees plus years of your life.
How much does Form 15 and Form 16 encumbrance certificate cost in Bangalore in 2026?
The Karnataka stamps and registration department charges roughly Rs 30 per year of the search period, plus user charges for the online portal. So a 30-year Form 15 search on a land parcel costs in the range of Rs 900 to Rs 1,200 in government fees.
A lawyer-led review of that EC, cross-checked against the mother deed, khata and tax records, is a separate professional fee. At Legal Brigade, we keep it as a flat fee, no padding, typically a fraction of what large firms quote for the same scrutiny.
If you want a sense of what that looks like for your specific property, you can book a free property consultation and we'll tell you straight.
Self-check vs lawyer-led EC review - which one do you need?
Plenty of buyers pull the EC themselves and read it. That's fine for a first look. It is not the same as a lawyer-led review.
| Point | Self-check of EC | Lawyer-led EC review |
|---|---|---|
| What you get | A PDF with entries | Interpretation of each entry against the title chain |
| Time | Hours to days | 48 to 72 hours for a full opinion |
| Risk caught | Obvious entries | Unreleased mortgages, partition gaps, prior sales, attachments |
| Cross-checked with | Nothing | Mother deed, khata, tax records, survey records |
| Useful for | Preliminary filtering | Actual purchase decision |
Takeaway: Pulling the EC is step one. Reading it against the full title chain is what protects your money.
Karnataka charges 5% stamp duty plus 1% registration on properties above Rs 45 lakh (Karnataka Stamp Act schedule, 2025). On a Rs 1 crore flat, that is Rs 6 lakh in government charges alone. Spending a few thousand on a proper EC and title review before you commit that kind of money is not an expense. It is insurance.
Do you need Form 15 for a bank loan?
Yes. Most banks and housing finance companies insist on a Form 15 EC covering the last 13 to 30 years before they sanction a loan. They want to see the full transaction history because the property is their collateral. If the EC throws up an unreleased charge, the loan will not move until it is cleared. In my experience, banks are stricter about this than buyers are, which tells you something.
How often should you refresh the EC?
An EC is a snapshot as of the date it is generated. If you pulled it three months ago and are registering now, pull it again. Transactions can be registered in the gap. I've seen a mortgage registered between the EC date and the registration date. It happens. Always take a fresh EC within 15 days of registration.
Final word on Form 15 and Form 16
Form 16 is a glance. Form 15 is the full picture. If you are buying property in Bangalore, ask for Form 15, cover the full chain period, and get it read properly against the mother deed and khata. That is the difference between a clean purchase and a decade in court.
If you want to read more on how we approach these checks, there are more property buying guides on our site. And if you have a specific property in front of you right now, get the EC checked before you pay the next rupee. Twenty years in this practice has taught me one thing: the paperwork always tells the truth. You just have to know how to ask it.
Frequently Asked Questions
What is the difference between Form 15 and Form 16 in an encumbrance certificate?
Form 15 is the EC you get when the property has no registered transactions at all in the period you asked for. Form 16 is the EC that lists every registered transaction - sale deeds, mortgages, gifts, leases, releases - that touched that property during the search period. In plain terms, Form 15 says the sub-registrar found nothing, Form 16 says here is everything he found. Both are issued under the Karnataka Registration Act, 1908, and both come from the same Sub-Registrar Office that holds jurisdiction over the property.
Which one do I need for a home loan or a resale?
Banks and buyers almost always want Form 16 for a 30-year search period. Form 15 is only useful when you are confirming that a plot or flat has stayed clean and unsold in a specific window, say the last 12 or 15 years. If you are buying resale property in Bangalore, insist on Form 16 for 30 years. I have seen buyers accept a 12-year EC and later discover a 1998 mortgage that was never cleared - that is how families end up in court.
How much does an encumbrance certificate cost in Bangalore?
Through Kaveri Online Services, the government fee is Rs 15 per year of search plus a small service charge, so a 30-year EC for one property works out to roughly Rs 450 to Rs 500 in government fees. If you walk into a Bangalore One centre or use an agent, expect to pay Rs 800 to Rs 1,200 for the same document because of handling charges. A lawyer doing it as part of full title verification will fold the EC cost into the overall fee, which is how I prefer to work - you get the EC plus the reading of it, not just a printout.
How long does it take to get Form 15 or Form 16 in Bangalore?
On Kaveri Online, a clean EC usually comes back in 3 to 7 working days. If the Sub-Registrar Office is short-staffed or the property has a messy history, it can stretch to 15 days. I tell clients to budget two weeks for the EC alone before they set any registration date. Anyone promising an EC in 24 hours is either using a contact at the office or bluffing, and neither is a good sign for your transaction.
Can I do property verification myself or do I need a lawyer?
You can pull the EC yourself - it is a public document and Kaveri makes it accessible. What you cannot easily do is read it. A Form 16 entry like 'Release Deed, Document No. 45/2003' means nothing to a first-time buyer but tells me whether a co-owner was bought out or a loan was cleared. In 20 years, I have caught at least 40 cases where the EC looked clean on the surface and hid a pending mortgage or a defective mother deed. Get the EC yourself if you want, but get a lawyer to read it before you pay any advance.
Why does my EC show Form 15 for 30 years and Form 16 only for the last 5 years?
That happens when the older records are not digitised or were indexed under a different survey number or door number. The Sub-Registrar can only report what is in his register for the exact property description you gave. If the older sale deeds were registered under an old survey number that later got subdivided, the search will miss them. Always give the lawyer the parent document and the current khata so the search covers every alias the property has carried.
Does a Form 16 EC guarantee the title is clear?
No, and this is the single biggest misunderstanding I deal with. The EC only tells you what was registered. It does not tell you about unregistered family partitions, a will that was never probated, a court attachment, or a builder's khata irregularity. Form 16 is one pillar of due diligence, not the whole building. You still need the mother deed, the 11E sketch, tax receipts, khata, and a physical inspection before you sign anything.
If you have a token advance sitting on a deadline and an EC in hand that you cannot fully read, do not sign the sale deed on hope. At Legal Brigade, a full title check including the Form 15 and Form 16 encumbrance certificate, mother deed scrutiny, and khata verification usually comes back in 48 to 72 hours at a flat, transparent fee that we tell you upfront before we start. Send us the documents and we will tell you exactly where you stand, in writing. book a free property consultation.
